Claims.

This invention relates to improvements in shoes andshoe bottom units.The invention is illustrated with special reference to its embodiment inshank pieces for turn shoes commonly known 5 as turn shanks although itmay advantageously be embodied also in reinforced insoles for McKaysewedshoes or other shoes in which the insoles are initially cutsubstantially totheir finalmarginal contour.

One object of the present invention is to provide an improved shoebottom unit for use in conjunction with a heel-attaching fastener tobrace the heel and stiffen the shank portion of a shoe.

To the accomplishment of this object, one feal5 ture of the inventionconsists in a shoe bottom unit prepared for the reception of a heelfastener and comprising a shoe bottom piece, for example, a turn shankfiller piece, a reinforcing or stiffening member, such as a metallicshank stifiener, located at the outer side of the shoe bottom piece andhaving a heel-fastener-receiving hole therein, and aheel-fastener-retaining member located at the inner side of the shoebottom piece and having a heel-fastener-receiving hole therein, saidmembers and the shoe bottom piece being secured together, with saidholes in alinement and unobstructed, by means of one of said membersextending through the shoe bottom piece and having holding engagementwith the other of said members.

As herein illustrated, a heel-fastener is employed which consists of anordinary wood screw and the heel-fastener-retaining member consists of athin metallic plate having a hole which is smaller than the head of thescrew so that the screw cannot be pulled outwardly through the shoebottom piece but will be permanently retained in position to fasten theheel securely to the shoe. The illustrated .shoe bottom piece or .0 turnshank filler piece has a hole formed therein for receiving the screw andmeans is provided for securing together the component parts of the shoebottom unit or turn shank piece consisting of prongs struck from thematerial of the screwfastener-retaining plate. The illustrated prongsproject downwardly from the edge of the hole in the plate; extendthrough the hole in the filler piece and through the hole in theshankstiffener; are clenched over the edges ofthe hole in the shankstiffener; and are arranged around the edge of the hole so as not tointerfere with the passage of the attaching screw therethrough. Also, asillustrated, the retaining plate is made large enough to serve as aclenching plate for lasting tacks employed to secure the upper to thefiller piece, thereby insuring the production of a nailless heel seat inthe shoe. Furthermore, the heel portion of the filler piece ispreferably split to provide an integral flap for use in covering theclenching plate as well as the head of the heelo0 attaching screw.

Considered in another aspect, the invention resides also in a shoehaving an improved shoe bottom unit incorporated therein, the shoecomprising a heel and a heel-attaching-fastener 05 which, as hereinillustrated, extends through the component members of the shoe bottomunit and cooperates therewith in bracing the heel and stiffening theshank portion of the shoe.

The invention will be explained with reference to the accompanyingdrawing in which,

Fig. 6 is a perspective view of the improved shoe bottom unit in theform of a reinforced insole for use in shoes other than turn shoes.

Referring first to Figs. 1 to 5, inclusive, which show the inventionembodied in a composite shank piece for a turn shoe, the improved shankpiece comprises a filler piece 10 made of leather board or othersuitable material, a reinforcing member consisting of a metallic shankstiffener strip 12 which is located in a longitudinal groove 14 (Fig. 2)in the outer side of the filler piece, and a heel-fastener-retainingmember consisting of a thin metallic plate 16 which is located at theinner side of the filler piece 10 beneath a thin flap 18 which is formedintegrally with the filler piece by splitting the rear portion of thelatter.- As shown, the filler piece 10 is shaped in marginal contour tocorrespond to the contour of the interior of the heel and shank portionsof a shoe. 100 The shank stiffener 12 is made long enough to underliethe heel seat portion of the filler piece and the rear portion of theshank stiffener is provided with a circular aperture 20 (Fig. 2) forreceiving a heel-atlaching screw 22 shown in Fig. 5. 105 Thefastener-retaining plate 16 is shown as being cupped to conform to theconvexity of the heel portion of the foot and it is provided with acircular aperture 2a for receiving a heel-attaching screw, the aperturebeing adapted, as herein-= 1 after explained to prevent the head of theattaching screw from being pulled outwardly through the plate 16 andthus the plate 16 serves to retain the screw in heel-attaching positionin the shoe. As shown, the retaining plate 16 has a marginal contourcorresponding to that of the heel portion of the filler piece 10, thisconstruction adapting the retaining plate to serve also as a-clinchingplate for clinching the points of the lasting tacks employed to securethe upper of the shoe to the filler piece. For the purpose of receivingclinching plate 16 at the edge ofthe hole 26, these prongs beingconveniently formed by means of a punch die employed in making the hole24.

In assembling the above described parts the clinching plate 16 isapplied beneath the flap 1'8 with the prongs 28 extending through thehole 26 in the filler piece and the shank stiffener 12 is laid in thegroove 14 of the filler piece, the hole 20 being placed over the outerends of the prongs 28. The outer ends of the prongs 28 are then rolledover the edge of the hole 20 in the shank stiffener as shown Figs. 2 and4, so as rigidly to secure both clinching plate 16 and the shankstiffener 12 to the filler piece with the holes in the clinching plate,the filler piece and the shank stiffener in coaxial alinement. Theconstruction is such that lower portions of the prongs will snuglyengage the shank of the heel-attaching screw, while the portions of theprongs adjacent to the clinching plate are curved or bent suificientlyto provide a seat for the tapering lower faceof the head of theattaching screw.

In Fig. 5 the composite shank piece above-described is shownincorporated in a turn shoe comprising also an upper 30, a tread sole32, and a heel 34. The margin of the upper 30, as shown, is lasted overthe turn shank filler piece 10 and is secured to the latter by means oflasting tacks one of which is indicated at 36, the points of the lastingtacks being clinched over against the upper side of the fillerpiece bythe action of the clinching plate 16 so that a nailless heel seat isprovided within the s'hoe.. The heel attaching screw 22 extends throughthe hole 24 in the clinching plate 16,the hole 26 in the filler piece 10and the hole 20 in the shank stifiener 12 and is screwed into the heel.The prongs 28 snugly embrace the shank portion of the screw 22 but areshaped near their base portions, as best shown in Fig. 4 to conform tothe bevel of the head of the screw sothat the upper surface of the screwhead will be substantially flush with the upper surface of the clinchingplate 16. As shown, the head of the screw 22' and the upper surface ofthe clinching plate 16 are covered by means of the flap 18 of the fillerpiece so that'no metal is exposed and visible in the interior of theshoe bottom. The shank stiffener 12 is countersunk within the groove 14to such an extent that its outer surface is substantially flush with theouter surface of the'filler piece thus enabling the tread sole to lieclose to the filler piece. The countersinking of the shank stiffener inthe filler piece also insures that the shank stifiener "i lll notinterfere with the pulling over and lasting of the upper margins. Theabove-described construction is such that the heel-attaching screwco-operates with the'members of the composite shank piece in bracing theheel and stiffening the shank portion of the shoe.

The construction shown'in Fig. 6 is similar to that shown in Figs. 1 to4, inclusive, except that the shank stiffener 12 and the clinching plate16 are shown assembled with a full length insole 100 instead of a fillerpiece such as the filler piece 10. A shoe bottom unit is thus providedfor use in shoes other than turn shoes, for example, Mc- Kay-sewed shoesand shoes wherein an outersole is secured to the shoe partiallyor whollyby means of cement.
